452.16 = 3.1416 r^2
r^2 = 452.16 / 3.1416
r^2 = 143.93
r = 11.997
C = 2 (3.1416) (12) =75.38 m
Answer:
-4
Step-by-step explanation:
Parallel to y= - 1, and passing through (2,-4):
Answer: The standard deviation of the sampling distribution is 0.0110
Step-by-step explanation:
The standard deviation of the sampling distribution is given by :-
, where p = population proportion and n = sample size.
Let 
denote the proportion in the sample who say they support the increase.
As per given :
Then , the standard deviation of the sampling distribution is
Hence, the standard deviation of the sampling distribution is 0.0110.
The x- and y-intercepts of the graphs of the function described are; (2,0) and (4,0) respectively.
<h3>What are the x- and y-intercepts of the graph of the function?</h3>
It follows from the task content that the function given is; f(x) = −2| x +1 | + 6.
Since the x- and y-intercepts corresponds to x and y values for which y and x are zero respectively, it follows that;
x -intercept is;
0 = -2(x+1) + 6
2x = -2 +6
2x = 4
x = 4/2 = 2
y-intercept is;
y = -2(0+1) +6
y = 4.
